A Human-Machine Interface (HMI) is a system that allows humans to interact with machines or devices. It serves as a bridge between the user and the machine, enabling control and monitoring of various functions. Common examples of HMIs include touchscreens, buttons, and graphical displays found in devices like industrial equipment, home appliances, and automobiles. HMIs are designed to be user-friendly, ensuring that people can easily understand and operate machines without extensive training. They often incorporate visual elements, such as icons and menus, to simplify navigation and enhance user experience. Effective HMIs improve efficiency and safety in various applications, from manufacturing to healthcare.
